One
possible
version：
Life
in
the
future:
for
better
or
worse?
Many
students
are
optimistic
about
the
next
fifty
years.
They
think
that
the
world
will
be
a
better
place
than
it
is
now
and
our
life
will
be
greatly
improved.
What’s
more,
people
will
have
a
higher
standard
of
living
and
live
longer.
However,
other
students
are
worried
about
the
future.
They
say
the
world
will
become
more
crowded.
Therefore,
we
will
have
even
more
environmental
problems
and
live
in
a
world
with
less
energy
available.
But
in
my
opinion,
I
think
we
will
find
ways
to
solve
our
problems
and
everyone
will
live
more
happily.
